Exopod uniarticulate, longer than endopodal article 1, with one middle and two distal simple setae. Distribution. So far known only from the type locality. Remarks. Parakonarus kajii sp. nov. is the ninth species described in this genus ( cf. Anderson 2016). Among its eight congeners, both sexes have been described in six species: P. fairgo (Bamber, 2005), P.juliae (Morales-Núñez et al ., 2013), P. kopure Bird, 2011, P. provincialis (Dollfus, 1898), P. robertsoni Edgar, 2012, and P. sozo Bamber, 2013. Parakonarus corrigendum Bamber, 2013 lacks information from females, and P.oregmus Bamber, 2013 lacks information from males. Parakonarus kajii is the seventh member with male and female information, and the first case where the male and female pair was confirmed by molecular data. Male P. kajii has a well-developed digitiform process on the ventral margin of the chelipedal carpus (Fig. 4D, d 1). This feature is also found in male P. juliae (Morales-Núñez et al . 2013); however, the positions of the three simple setae on the process are different between the two species. In P. kajii , one ventro-subproximal, one outer, and one inner setae are distributed in the basal half of the process. In contrast, in P.juliae , one seta is placed at the tip of process, and the other two are located near the base of the process and distal to the process (Morales-Núñez et al . 2013: fig. 8B, C); this pattern is also found in P. corrigendum , P. fairgo , and P. sozo (Błażewicz-Paszkowycz and Bamber 2012; Morales-Núñez et al . 2013). These differences indicate that, even though the shape of the process is similar, the region of origin of the process is not identical: the process in P.kajii must form as an expansion of the exoskeleton originating more distally on the carpus than in P.juliae . In terms of the setal positions, male P. kajii closely resembles male P.kopure (Bird 2011), but can be distinguished from the latter by having the ventral process on the chelipedal carpus longer than wide (wider than long in P. kopure ); the inner comb-row on the chelipedal propodus comprising 16 setae (about nine in P. kopure ); and the dactylus and unguis of pereopods 4–6 fused (separate in P.kopure ). Parakonarus robertsoni has more than 10 ventral simple setae on the chelipedal merus in both sexes, and males have four ventral simple setae on the chelipedal carpus (based on figs 13 CH and 17 CH in Edgar 2012), which distinguish this species from P.kajii . Very limited morphological information is available for P. provincialis , but it differs from P. kajii in that the ventral process on the chelipedal carpus is wider than long (longer than wide in P. kajii ), the chelipedal dactylus lacks a ventroproximal triangular process (present in P. kajii ), and the uropodal endopod has five articles (four in P. kajii ) (Dollfus 1898). Among the eight species with information on females, the females of P. kajii , P. kopure , P. robertsoni , and P. sozo have a short body, with pereonite 4 shorter than wide. Female P. kajii differs from female P. kopure in that the ventrodistal seta on the pereopod-1 merus is short, or 0.28 times as long as the merus width (long, or 1.20 times as long as the merus width in P. kopure ); the pereopod-1 unguis is 1.35 times as long as the dactylus (1.77 times as long as the dactylus in P. kopure ); the carpi of pereopods 2 and 3 lack the ventrodistal spiniform seta (present in P. kopure ); the propodal palm of the cheliped has two inner simple setae at the insertion of the dactylus (five in P. kopure ); and article 2 of the maxillipedal palp has one mid-outer and one outer distal simple setae (one mid-outer seta only in P. kopure ) (Bird 2011). Female P. kajii differs from female P. robertsoni in having the chelipedal merus and carpus respectively bearing six and three ventral simple setae (more than 1 : Published as part of Kakui, Keiichi, Uyeno, Daisuke & Naruse, Tohru, 2019, First Molecularly Confirmed Conspecific Male and Female Pair in Konariinae (Crustacea: Tanaidacea), with the Description of a New Species, pp. 49-60 in Species Diversity 24 (1) on pages 51-58, DOI: 10.12782/specdiv.24.49, http://zenodo.org/record/4585200 : {"references": ["Bird, G.

Parakonarus kajii sp. nov. is the ninth species described in this genus ( cf. Anderson 2016). Among its eight congeners, both sexes have been described in six species: P. fairgo (Bamber, 2005), P.juliae (Morales-Núñez et al ., 2013), P. kopure Bird, 2011, P. provincialis (Dollfus, 1898), P. robertsoni Edgar, 2012, and P. sozo Bamber, 2013. Parakonarus corrigendum Bamber, 2013 lacks information from females, and P.oregmus Bamber, 2013 lacks information from males. Parakonarus kajii is the seventh member with male and female information, and the first case where the male and female pair was confirmed by molecular data. Male P. kajii has a well-developed digitiform process on the ventral margin of the chelipedal carpus (Fig. 4D, d 1). This feature is also found in male P. juliae (Morales-Núñez et al . 2013); however, the positions of the three simple setae on the process are different between the two species. In P. kajii , one ventro-subproximal, one outer, and one inner setae are distributed in the basal half of the process. In contrast, in P.juliae , one seta is placed at the tip of process, and the other two are located near the base of the process and distal to the process (Morales-Núñez et al . 2013: fig. 8B, C); this pattern is also found in P. corrigendum , P. fairgo , and P. sozo (Błażewicz-Paszkowycz and Bamber 2012; Morales-Núñez et al . 2013). These differences indicate that, even though the shape of the process is similar, the region of origin of the process is not identical: the process in P.kajii must form as an expansion of the exoskeleton originating more distally on the carpus than in P.juliae . In terms of the setal positions, male P. kajii closely resembles male P.kopure (Bird 2011), but can be distinguished from the latter by having the ventral process on the chelipedal carpus longer than wide (wider than long in P. kopure ); the inner comb-row on the chelipedal propodus comprising 16 setae (about nine in P. kopure ); and the dactylus and unguis of pereopods 4–6 fused (separate in P.kopure ). Parakonarus robertsoni has more than 10 ventral simple setae on the chelipedal merus in both sexes, and males have four ventral simple setae on the chelipedal carpus (based on figs 13 CH and 17 CH in Edgar 2012), which distinguish this species from P.kajii . Very limited morphological information is available for P. provincialis , but it differs from P. kajii in that the ventral process on the chelipedal carpus is wider than long (longer than wide in P. kajii ), the chelipedal dactylus lacks a ventroproximal triangular process (present in P. kajii ), and the uropodal endopod has five articles (four in P. kajii ) (Dollfus 1898). Among the eight species with information on females, the females of P. kajii , P. kopure , P. robertsoni , and P. sozo have a short body, with pereonite 4 shorter than wide. Female P. kajii differs from female P. kopure in that the ventrodistal seta on the pereopod-1 merus is short, or 0.28 times as long as the merus width (long, or 1.20 times as long as the merus width in P. kopure ); the pereopod-1 unguis is 1.35 times as long as the dactylus (1.77 times as long as the dactylus in P. kopure ); the carpi of pereopods 2 and 3 lack the ventrodistal spiniform seta (present in P. kopure ); the propodal palm of the cheliped has two inner simple setae at the insertion of the dactylus (five in P. kopure ); and article 2 of the maxillipedal palp has one mid-outer and one outer distal simple setae (one mid-outer seta only in P. kopure ) (Bird 2011). Female P. kajii differs from female P. robertsoni in having the chelipedal merus and carpus respectively bearing six and three ventral simple setae (more than 1 : Published as part of Kakui, Keiichi, Uyeno, Daisuke & Naruse, Tohru, 2019, First Molecularly Confirmed Conspecific Male and Female Pair in Konariinae (Crustacea: Tanaidacea), with the Description of a New Species, pp. 49-60 in Species Diversity 24 (1) on pages 51-58, DOI: 10.12782/specdiv.24.49, http://zenodo.org/record/4585200 : {"references": ["Bird, G.
